speeineation forming part of Letters Patent No. 54,91 2, dated May 22,1866.

To all whom it may concern.-

Be it known that I, JACOB B. HYZER, of Janesville, in the county of Rockand State of Wisconsin,have invented a new and Improved Heat-RadiatingAttachment to Stoves; and I do hereby declare that the following is afull, clear, and exact description of the construction and operation ofthe same, reference heing had to the accompanying drawings, making apart of this specification, in which- Figure l is a perspective Viewwith the cover A removed. Fig. 2 is a top view with the cover A removedand a portion of the upper plate, B, broken away, showing the damperSturned down or back. Fig. 3 is also a top view similar to Fig. 2,except the damp er S is turned up. Fig. 4 is a transverse verticalsection, showing the arrangement of the iues and air-chambers.

To enable others skilled in the art to make and use my invention, I willproceed to de-` any desired form or pattern and of any suitablematerial, providing it with the necessary appendages, as a door, O, forthe admission ci' fuel, a suitable support, as the legs N, and anorifice, P, with a closing-cap, Q, to regulate the admission of air.

On the stove I construct the chamber I, which may either rest on theupper plate, K, or mainly cast in connection therewith.

From the stove (usually from the front portion) I run a series of iues,F, that connect the stove with a hot-air chamber, T, Fig. 4, whichhot-air chamber is formed between the plates B and E. The chamber T isalso connected to the lower chamber, l, by means of two series of flues,G and H, and is divided by the partition U into two separate apartmentsconnected by the damper S. The two series ot ues F and Gr open into thefront apartment of this chamber, While the other series, H, opens intothe rear apartment, from whence issues the smoke-pipe D.

The damper S is operated by the rod It, and the chamber I should have anorifice in its end or rear portion to'allow the soot and ashes thatcollect in the chamber to be removed.

When the stove is in operation, by opening the damper S (by turning itdown or back to the position shown in Fig. 2 and by dotted lines in Fig.4) a direct draft is obtained from the stove through the series of luesF into the front apartment of chamber T, and thence through the rearapartment into the smokedue D; but by closing the damper S (by turningit up to the position shown in Figs. 3 and 4) the heated air, smoke,arid iiame must pass up the series of iiues F into the front apartmentof the chamber T, thence down through the series of iiues G intothechamber I, thence up 'again through the series of lilies H, and thenceinto the smoke-tlueD.

It will be observed that a heat-radiating attachment to stovesconstructed as herein described possesses a greater amount of directradiating-surface, or of surface iu connection with which the air to bewarmed is brought, than the heat-radiating attachments now in use, andconsequently its heating capacity is greatly increased.

It will also be observed that the hot'air chambers T and I increase theabsorption,

and consequently the radiation, of heat, inasmuch as the currents in thedues do not pass continuously through the chambers, but are therebybroken into eddies, or in ameasure cease.

The nature of my invention consists in the employment, in connectionwith a series of ascendin g fines from the stove, of a hot-air chamber,with a partition and damper so arranged that when the damper is open adirect draft is had from the stove, through the tlues and chamber, intothe smoke-pipe; but when the damper is closed the heated air, smoke, andtlame must pass from the chamber through a second and descending seriesof ilues into an other hot-air chamber, and thence through a third orreturn series of flues into au apartment'of the first chamber, fromwhence the smoke, bereft of most of its caloric, is allowed to escapeinto the smoke-pipe.

I am aware that ascending and descending iues havebeen used,and I do notclaim them apart from the manner in which they are used; but

What I do claim, and for which I desire Letters Patent of the UnitedStates, is

The combination and arrangement of the dues F and hot-air chamber T(when constructed with the partition U and damper S) with the iiues G,hot-air chamber I, and return-tlues II, substantially as and for thepurpose set forth.
